CVE-2026-64544

In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetric_keys - fix OOB read in pefile_digest_pe_contents pefile_digest_pe_contents() computes the trailing-data hash length as pelen - (hashed_bytes + certs_size). A crafted PE can make the addition exceed pelen, causing the unsigned subtraction to underflow to ~4 GiB. This is passed to crypto_shash_update() which reads out of bounds and panics on unmapped vmalloc guard pages. BUG: unable to handle page fault for
